Murata introduces 0201 inch audio line noise filter for smart phones
2018-02-06 | ReturnOverview
Murata Manufacturing Co., Ltd. has introduced the NFZ03SG_SN series of audio line noise filters at a size of 0201 inch size (0.6×0.3mm), which is the smallest size in the industry. Mass production of these products began in January 2018.
In recent years, high sound quality has been emphasized as one of the selling points of smart phones and portable audio devices, and audio quality level has been a significant feature by which consumers choose devices. In order to counteract noise, the audio circuits used in these devices must include a noise suppression filter. However, noise suppression filters produce audio distortion, and thus cause a loss in sound quality.
NFZ03SG_SN series make use of our proprietary material technology to suppress audio distortion that occurs when audio circuits are used, in order to efficiently eliminate noise while maintaining high sound quality.
Characteristics
。330 to 1600 ohm at 900 MHz
。Designed to have an impedance peak at communication frequencies
。0.6 x 0.3 mm size
。Impedance characteristics
。Audio distortion characteristics (THD+N)
